Daily Fantasy Sports and Gambling: Overview.

Daily fantasy sports (DFS) emerged in the first decade of the twenty-first century, building upon the existing hobby of fantasy sports, in which participants compete by drafting fantasy teams of real-life athletes in a particular sport and earn points based on those athletes' actual achievements over the course of a season. Unlike regular fantasy sports, DFS shorten the length of such competitions to as little as a day or a week, enabling participants to engage in a larger number of competitions and adjust their fantasy lineups as a sport's season progresses. With the rise of major forces in the industry such as the companies FanDuel and DraftKings—founded in 2009 and 2012, respectively—DFS became both a cultural phenomenon and a profitable industry in the United States, and leading DFS companies soon began to form lucrative partnerships with athletic leagues and leaders in the professional sports industry.
